My sojourn in the world of 8th grade math continues. As pointless and repetitive as the exercises are, the feeble attempts by the textbook authors to make the problems relevant are worse. Here’s a “real world” example of linear equations:
- You and your friend together sell 58 tickets to a raffle.
- You sold 14 more tickets than your friend.
- How many did you and your friend each sell?
Even if an 8th grader were willing to consider a world in which this kind of partial information were available (maybe Enron did accounting like this?) and someone cared about the answer, why would it matter?
Readers: What’s an example of a system of linear equations that has obvious practical value, as perceived by an 8th grader?
